Logix Platforms Allen-Bradley Logix platforms provide a single integrated control architecture for

discrete, drives, motion, and process control.

The Logix platforms provide a common control engine, programming software

environment, and communication support across multiple hardware platforms. All

Logix controllers operate with a multitasking, multiprocessing operating system and

support the same set of instructions in multiple programming languages. One

RSLogix™ 5000 programming software package programs all Logix controllers. And

all Logix controllers incorporate the NetLinx Open Network Architecture to

communicate via EtherNet/IP, ControlNet, and DeviceNet networks.

1756-SG001G-EN-P — March 2004

ControlLogix

System Overview

What’s New in Version 13:

The ControlLogix®system provides sequential, process, motion, and drive control

together with communications and state-of-the-art I/O in a small, cost-competitive

package. The system is modular, so you can design, build, and modify it efficiently -

with significant savings in training and engineering. A simple ControlLogix system

consists of a stand-alone controller and I/O modules in a single chassis.

Or use the ControlLogix system as a gateway. Include the communication modules you

need for connectivity to other networks. For this use, a controller is not required. The

ControlLogix Gateway integrates into existing PLC-based systems so that users with

existing networks can send or receive messages to or from other networks. For a

more robust system, use:

ymultiple controllers in a single chassis

ymultiple controllers joined across networks

yI/O in multiple platforms that is distributed in many locations and connected over

multiple I/O links

y1756-IB16ISOE and 1756-IH16ISOE modules

to record sequence of events

y1756-IG16 and 1756-OG16 TTL I/O modules

y1756-IA32 high-density, ac input module

y1756-EWEB enhanced web server module

y1756-M03SE 3-axes SERCOS module and

1756-L60M03SE controller with embedded

SERCOS interface

y1756-M02AS SSI feedback motion module

yredundant controller systems now support

two 1756-L55 controllers or one

1756-L6x controller

yredundant controller systems now support

the 1756-ENBT module

y1756-PSCA2 adapter module and 1756-CPR2

cable for redundant power supplies

1756-SG001G-EN-P — March 2004

Layout the System Lay out the system by determining the network configuration and the placement of

components in each location. Decide at this time whether each location will have its

own controller.

Place each controller’s I/O on an isolated network to maximize the performance and

to more easily accommodate future network or system configuration changes. If you

plan to share I/O, make sure the I/O is on a network that each controller can access.

Assume that Location A and Location B both require a controller and its own I/O.

Both controllers interact with time critical information. Panel C does not need a

controller and can be a gateway.

For a ControlLogix controller to control I/O modules, both the controller and the I/O

modules must be directly attached to the same network.

Evaluate what communications need to occur between controllers. If there is sporadic

information that is not time critical, use a message-based network such as an

EtherNet/IP (the information portion), Data Highway Plus, or the unscheduled portion

of a ControlNet network. If the information is time critical, such as

produced/consumed tags between controllers, use a ControlNet or EtherNet/IP

network.

I/O Location Controller in Panel A, Chassis 1 Controller in Panel B, Chassis 1

Panel A, Chassis 1 yes yes

Panel A, Chassis 2 yes no

Panel A, Chassis 3 yes no

Panel B, Chassis 1 yes yes

Panel B, Chassis 2 no yes

Panel C, Chassis 1 yes yes

1756-SG001G-EN-P — March 2004

Laying out a redundant system

The ControlLogix environment offers different levels of redundancy that you can

design into your system. These systems require additional hardware, so plan

accordingly. You can design redundant:

ymedia for ControlNet

ypower supplies

ycontroller chassis

Redundant ControlNet media

Requires:

y1756-CNBR ControlNet modules

ytwo identical ControlNet links

Redundant power supplies

Requires:

ytwo redundant power supplies, any combination of 1756-PA75R and 1756-PB75R

y1756-PSCA2 chassis adapter module, in place of the standard power supply

ytwo 1756-CPR2 cables to connect the power supplies to the 1756-PSCA adapter

yuser-supplied annunicator wiring to connect the power supplies to the input

modules, if needed

1756-SG001G-EN-P — March 2004

Redundant controller

chassis

Requires:

yone or two 1756-L55 controllers or one 1769-L6x controller in each redundant

chassis (contact your Rockwell Automation representative for the specific

firmware revision)

yat least one, but no more than five, 1756-CNB(R) series D, version 5.23 (or

greater) communication modules in each redundant chassis

yone 1757-SRM module in each redundant chassis

ythe redundant chassis can contain a 1756-ENBT communication module, but no

other I/O or communication modules can be in the redundant chassis

All I/O must be remote from the redundant controllers. ControlLogix redundancy

works with remote 1756 I/O, FLEX I/O, drives, operator interfaces, or any other

devices that can communicate with a ControlLogix controller over a ControlNet link.

To connect to other networks, bridge through another ControlLogix chassis (not one

of the redundant controller chassis)

Use the following checklist as a guide to completing your own system specification.

The inside of the back cover of this selection guide is a worksheet you can use to

record your selections.

99Step

1 Select I/O devices

Use a spreadsheet to record:

ylocation of the device

ynumber of points needed

yappropriate catalog number

ynumber of points available per module

ynumber of modules

2 Select motion control and drives requirements

To the I/O spreadsheet, add the number of required motion

modules.

3 Select communication modules

To the I/O spreadsheet, add the number of required

communication modules.

4 Select controllers

Select the appropriate controller based on:

yrequired controller tasks

ynumber of I/O points needed

ynumber of communication cards needed

yrequired controller memory

5 Select chassis

Determine the number of chassis you need.

6 Select power supplies

On the module spreadsheet, calculate power requirements.

7 Select software

Determine the software products you need to configure and

program your application.Based on the system design, determine

Selecting ControlLogix

I/O Modules

The ControlLogix architecture provides a wide range of input and output modules to

span many applications, from high-speed discrete to process control. The

ControlLogix architecture uses producer/consumer technology, which allows input

information and output status to be shared among multiple ControlLogix controllers.

Each ControlLogix I/O module mounts in a ControlLogix chassis and requires either

a removable terminal block (RTB) or a 1492 interface module (IFM) to connect all

field-side wiring. RTBs and IFMs are not included with the I/O modules. They must be

ordered separately.

1756 Digital I/O

Modules

The 1756 digital I/O modules support:

ywide variety of voltage interface capabilities

yisolated and non-isolated module types

ypoint-level output fault states

ychoice of direct-connect or rack-optimized communications

yfield-side diagnostics on select modules

In addition, you can select these types of digital I/O modules:

Description

These modules provide diagnostic features to the point level. These modules have a “D”

at the end of the catalog number.

These modules have internal electronic fusing to prevent too much current from flowing

through the module. These modules have an “E” at the end of the catalog number.

These modules have individually isolated inputs or outputs.

These modules have an “I” at the end of the catalog number.
